304 thiab 316 stainless hlau yog ob hom stainless hlau cov ntaub ntawv. Qhov sib txawv ntawm lawv feem ntau yog nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg thiab daim ntawv thov teb. 316 stainless hlau muaj ntau dua chromium thiab npib tsib xee cov ntsiab lus ntau dua 304 stainless hlau, uas ua rau 316 stainless hlau muaj zoo corrosion kuj, tshwj xeeb tshaj yog tawm tsam chloride media. Yog li ntawd, 316 stainless hlau yog tsim nyog rau siv nyob rau hauv ib puag ncig uas muaj corrosion kuj yuav tsum tau ntau dua, xws li seawater ib puag ncig los yog tshuaj industries. 304 stainless hlau feem ntau yog siv rau hauv kev siv dav dav xws li cov khoom siv hauv chav ua noj, cov khoom siv hauv tsev, thiab lwm yam.
Thaum nws los txog rau 304 thiab316 stainless hlau, peb tuaj yeem kawm paub ntau ntxiv txog lawv qhov kev ua tau zoo. Ntxiv nrog rau lawv cov tshuaj muaj pes tsawg leeg, ob lub stainless hlau kuj txawv ntawm lawv cov khoom siv kho tshuab thiab kev ua haujlwm. 316 stainless hlau feem ntau muaj zog tensile ntau dua thiab compressive zog, tab sis tej zaum yuav muaj qis plasticity kuj hais lus. Tsis tas li ntawd, cov khoom siv kho cua sov ntawm 316 stainless hlau tsis hloov pauv raws li 304 stainless hlau, yog li xav tau ntau dua thiab kev txawj ntse hauv kev ua thiab kev tsim. Tsis tas li ntawd, muaj lwm yam khoom siv hlau tsis zoo, xws li 304L thiab 316L, uas muaj cov ntsiab lus qis dua thiab tsim nyog rau kev zam kom tsis txhob muaj cov nag lossis daus thaum vuam. Yog li ntawd, thaum xaiv cov ntaub ntawv stainless hlau, ntxiv rau kev txiav txim siab nws cov kev tiv thaiv corrosion, nws tseem yuav tsum tau xav txog nws cov khoom siv kho tshuab, kev ua haujlwm thiab cov kev xav tau ntawm cov ntawv thov tshwj xeeb hauv cheeb tsam txhawm rau xaiv cov khoom tsim nyog tshaj plaws.
Thaum txuas ntxiv peb txoj kev nkag siab ntawm 304 thiab 316 stainless hlau, peb tuaj yeem xav txog lawv cov khoom siv corrosion hauv ib puag ncig tshwj xeeb. Vim yog cov ntsiab lus molybdenum, 316 stainless hlau feem ntau muaj kev tiv thaiv corrosion ntau dua li 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions, xws li dej hiav txwv lossis dej ntsev. Qhov no ua rau316 stainless hlaukev xaiv cov khoom tsim nyog rau kev siv nyob rau hauv marine ib puag ncig los yog tshuaj industries. Tsis tas li ntawd, qhov kev ua tau zoo sib txawv ntawm ob lub stainless steels nyob rau hauv high-temperature ib puag ncig tuaj yeem tshawb nrhiav ntxiv, nrog rau lawv cov kev siv hauv kev lag luam tshwj xeeb xws li kev ua zaub mov thiab khoom siv kho mob. Nrog rau kev nkag siab tob dua, peb tuaj yeem xaiv cov khoom siv hlau tsis zoo rau cov khoom siv sib txawv kom ntseeg tau tias nws ua tau zoo nyob rau hauv ib puag ncig thiab tej yam kev mob.
Xaiv 304 lossis 316 stainless hlau nyob ntawm qhov kev thov tshwj xeeb. Feem ntau hais lus, 304 stainless hlau muaj kev tiv thaiv corrosion zoo thiab tsim nyog rau qhov chaw sab hauv tsev thiab sab nraum zoov, thaum 316 stainless hlau muaj kev tiv thaiv corrosion ntau dua vim tias nws muaj molybdenum thiab tsim nyog siv rau hauv qhov chaw muaj corrosive heev, xws li dej hiav txwv. Environmental lossis chemical kev lag luam. Yog li, nws yog qhov kev coj ua zoo tshaj plaws los xaiv 304 lossis 316 stainless hlau raws li kev siv tshwj xeeb thiab kev xav tau.
